Another thing that is nice to have is a presta to schrader adapter (assuming you have presta valves).

This will let you go to any gas station air pump and fill up your bike tires. I've never had to use it, but it cost about 2.00, and fits in my small patch kit, so its cheap insurance.

I've yet to break a plastic tire lever. I even used my plastic tire levers to help mount my notoriously difficult to mount Vittoria Randonneur tires recently, without damaging even one of them.

As far as pumps go, I'd strongly recommend one with a hose, rather than one that connects the pump body directly to the valve. You're far less likely to break a valve that way.

I'm going to go ahead and be the one to say something a little bit the other way - when I started biking, I bought pumps, tubes, patch kits, etc, because I'd get a flat at least once or twice every year.

But then they came out with puncture resistant tires. And - while I still carry a pump, a spare tube, and a patch kit - I've only had 2 flats, and those were on the inside of the wheel with new tubes (bad tube I guess). (And this is also why I don't carry CO2 - I almost never use it, and when I would I'd just end up forgetting to replace the empty cannister at the end of the ride.)

I really thought the Topeak Road Morph and the other one here in the thread were cool, and I own the Road Morph, but - with flat resistant tires, I just don't think they're worth the additional bulk vs a traditional and smaller pump that can mount under the water bottle cage. For a commuter bike, I also prefer a pump small enough to keep in one main bag on the back so I can just take the bag off the bike when going inside and not have to worry about carrying anything else with me. And unless you actually ride with a pannier, the full size road morph is just to big (plus it's difficult to mount on the frame).

The **Mini** Morph isn't bad for size, really all you need for a pump is something that will get enough air in your tire to get you home - especially if your commute is only 4 miles.

(There are exceptions - if you store your bike inside at work, if you are carrying a pannier, etc etc, this is just what I've found for my setup).
